Kaur, S., Kremer, M., Mullainathan, S.

Self-control problems change the logic of agency theory by partly aligning the interests of the firm and worker: both now value contracts that elicit future effort. Findings from a year-long field experiment with full-time data entry workers support this idea. First, workers increase output by voluntarily choosing dominated contracts (which penalize low output but give no additional rewards for high output). Second, effort increases closer to (randomly assigned) paydays.

This RCT will pilot Self-Accelerated Startups (SAS), a new peer-selection based entrepreneurship support model for idea-stage companies and student startups that uses collective bootstrapping on the lines of self-help groups in the social sector. In this model, prospective entrepreneurs meet regularly in groups for a pre-defined mentorship period and make small monthly contributions to a “seed fund”. At the end of this phase, the self-mobilized corpus is awarded as startup capital to one or two members by the rest of the peer group in return for equity in these startups.

Many resources, such as business acumen are thought to feed into entrepreneurial success. However, an open question is whether the tools and frameworks available to nascent startups are causally related to their successes in the areas of financing, employment and revenue growth, valuations, etc. In this study, we use a large-scale RCT to assess the impact of entrepreneurship skills training on startup decisions and outcomes across the U.S. In the study, startups associated co-working spaces are offered payment to complete a series of surveys tracking their outcomes over two years.

Higuchi, Y., Namb, V. H., Sonobec, T.

A randomized controlled trial of short-term management training for small manufacturers was conducted in two study sites in Vietnam and collected follow-up data repeatedly for
two years to assess longer-term impacts than the existing studies of management training.

Heite, J., Rosendahl Huber L., Kleine, M.

The Innovation Voucher Program analyzed in this study operates as a randomized controlled trial (RCT). This allows estimating the causal effect of the voucher on innovation and growth measures of beneficiaries, as well as their business outcomes in general. As a result, the evidence might be used to enhance voucher schemes and to provide further policy advice on how to effectively support small and medium-sized enterprises and their innovation activities in the future.

Gertler, P.

This study aims to carry out an evaluation of the long-term impacts of an innovative school-based intervention designed to enhance the ability of youth to engage and succeed in both formal employment and entrepreneurial activities in Uganda, ultimately leading to improvements in livelihood. The findings will inform future interventions (in Uganda, Rwanda, and Kenya) to help more young people overcome obstacles to successful entrepreneurship and labor market participation, such as gender-related barriers, thereby improving their livelihoods and socioeconomic security.

McKenzie, D., Maloney, W., Iacovone, L.

Examines the differential impacts of group management consulting versus individualised management consulting on firm performace in Colombia, and whether management practices are partially responsible for the gap in firm productivity in developing countries. Results forthcoming.

Cho, Y., Honorati, M.

Entrepreneurship programmes have a strong positive effect on youths, particularly on labour-market activities and business-practice outcomes, and improve business knowledge and practice, particularly for existing entrepreneurs. However, there is no evidence that this translates into improved business performance and increased income.

Drexler, A., Fischer, G., Schoar, A.

Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. We conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics. The rule-of-thumb training significantly improved firms' financial practices, objective reporting quality, and revenues.

Knight, A., Baer M.

Interpersonal effects of physical space indirectly affect performance for group engaged in knowledge work. Physical space shapes performance indirectly by affecting group members' arousal and territorial behaviour, which together influence information elaboration. The physical context in which a group works can shape interpersonal dynamics and ultimately group performance.

Georgiadis, A., Pitelis, C.

We investigate the relationship between employees' and managers' training and firm performance using a policy intervention that randomly assigned training support to small‐ and medium‐sized enterprises in the UK accommodation and food service sector. Because the number of firms self‐selected into training exceeded available places, training was randomly assigned to some firms, resulting in a randomized natural experimental design that allowed us to identify the average effect of training on treated firms.

Haines, H.

This paper explores the effectiveness of goal setting and accountability within group-based entrepreneurship initiatives in creating human capital. The study uses a randomized cluster trial to compare the experimental and control groups of entrepreneurs. The results suggest that frequent goal setting and accountability in group settings provides a greater number of learning experiences and human capital development opportunities available to entrepreneurs than those that did not engage in the same level of goal setting.

Crépon, B., Duflo, E., Huillery, E., Pariente, W., Seban, J.

The Paris School of Economics proposed a project to the Haut-Commissariat aux Solidarités Actives (French Minister for Active Solidarity against Poverty) to evaluate the impact of one of Adie’s programs, CréaJeunes. The “Association pour le droit à l’initiative économique” (Adie), is an NGO that aids people in creating their own business. The program is designed to encourage and support young people employment and entrepreneurship, particularly in poorer neighborhoods.

Levitt, S., and Neckermann, S.

This meta-analysis of field experimental evidence on firm-employee relationships finds strong evidence that financial incentive increase output, and that non-financial approaches and social relations also have important impacts. However, many important topics have not been studied yet using field experiments, including recruiting, worker promotion, and training.

Chioda, L., Gertler, P.

Using an OLS regression estimator with clustered standard errors, the analysis finds that, out of the twelve outcome variables used to assess the effectiveness of the program of achieving its stated goals, they have reached their target for the outcome variables of business ownership, overall income level, community project ownership, savings behaviour and self-efficacy but not for the indicators of paidemployment prevalence, business or employment income, holding of a school leadership position, business planning, financial literacy or creativity.

Dupas, P.

A randomised field experiment in Kenya uses differing levels of subsidies for an innovative bed net to suggest that temporary subsidies help short-term adoption rates of new (health) technologies and can perhaps have an effect on long-term adoption rates due to the learning experience.

Bareket-Bojmel, L., Hochman, G., Ariely, D.

In the context of a semiconductor factory in Israel, experimenting with different types of incentives yielded results that provide some guidance for organisations trying to motivate their employees, showing that incentives of small magnitude can motivate employees to perform better at low or insignificant cost. Also, simply allowing employees to choose their preferred form of incentive can neutralize the possible negative effect of cash bonuses on intrinsic motivation.

Previous research in economics shows that compensation based on the pay-for-performance principle is effective in inducing higher levels of effort and productivity. On the other hand, research in psychology argues that performance-based financial incentives inhibit creativity and innovation. How should managerial compensation be structured if the goal is to induce managers to pursue more innovative business strategies?

Niederle, M., Segal, C., Vesterlund, L.

In the context of a lab experiment replicating the job/hiring market, this study reveals that prior to affirmative action, women, including high-performing women, fail to enter the competition, thus the actual performance costs of affirmitive action are negligible. This implies that the long-term effects are positive, as increasing the representation of "minorities" may improve mentoring possibilities, and change the perception of "minorities'" ability to hold a high-ranking position.

Paravisini, D. & Schoar, A.

This experiment provides direct evidence on how information technologies can lead to the decentralisation of decision-making processes within organisations, and how IT solutions may represent an effective and low-cost alternative to steepening or increasing monetary incentives. Providing credit scores increased the effort committees put into solving more difficult problems, increased committees' overall output, and reduced the need for higher-level manager involvement in the decision-making process.

Bloom, N., Eifert B., Mahajan, A., McKenzie, D., Roberts J.

This management-focused consultancy intervention in the Indian textile industry showed positive impact on overall firm productivity through improved quality, efficiency and reduced inventory, and the effects of the experiment appeared to continue over time.
